This project evaluates the potential of two aquatic plants, azolla and duckweed, for municipal wastewater treatment. The study was conducted in a laboratory-scale experiment, in which both plants were grown in wastewater collected from a local municipal treatment plant. The growth rate, nutrient removal efficiency, and the biomass production of both plants were evaluated. The results showed that both azolla and duckweed were able to remove a significant amount of nutrients, including nitrogen and phosphorus, from the wastewater, with high removal efficiency. Both plants also demonstrated rapid growth rates and high biomass production. However, azolla showed a slightly higher nutrient removal efficiency and biomass production than duckweed. Overall, these findings suggest that both azolla and duckweed have great potential for use in municipal wastewater treatment systems, particularly in areas with limited land and resources for traditional wastewater treatment methods.
